The use of covered stents in intracranial vascular structures is a feasible method to treat selected cases of intracranial giant aneurysms. It is suggested that patients who present with compressive mass effect caused by large or giant aneurysms are the best candidates for covered stent placement, but potential complications should be considered carefully before the stenting procedure.

Surgery is the first-line treatment for symptomatic patients with hemangioblastomas in the medulla oblongata. Good results can be achieved for the cystic or small solid tumors. Large solid tumors remain a surgical challenge due to arteriovenous malformation-like vascularization. Preoperative embolization is useful for large solid tumors. For asymptomatic tumors, careful long-term observation or radiosurgery could be chosen.
